The current invention is directed to a switch apparatus (6) for operating a surgical evacuator (14). The switch apparatus broadly comprises a surgical device (39) having a power unit (12), a vibration generator (10) for producing vibrations in response to the operation of the surgical device, a vibration sensor (22) for generating an output as a function of vibrations sensed, a control unit (23) for producing a control signal as a function of the vibrations produced by the vibration generator and a surgical evacuator for removing a waste product generated by the use of the surgical device. The vibration generator is adaptively coupled to the power unit. In addition, the control unit is adaptively coupled to the vibration sensor. The evacuator is responsive to the control signal and is activated or deactivated based on the operation of the surgical device. In one embodiment, the control unit is comprised of an amplifying means (34), a filter means (47), a frequency sensor means (37), a first delay circuit (38), a second delay circuit (40) and an output circuit (42). The amplifier means amplifies output from the vibration sensor and the frequency sensor means detects the frequencies generated by the vibration generator and produces a control signal in response to such detection. The control signal then turns the evacuator on or off.

Switch apparatus for operating an evacuator

The present invention is a filter system self contained within a treatment room for a medical procedure. The filter system is partially incorporated into a standard surgical arm. The filter is mounted on the control unit of the surgical arm, which is at the free end of the surgical arm. A vacuum device to create airflow through the filter is located distant from the filter, but still within the treatment room. The vacuum device is adapted to exhaust either into a portion of the treatment or the HVAC system of the facility in which the treatment room resides. Controls for the filter system are also incorporated into the control unit of the surgical arm.
